Google Chrome OS

I read something a while ago where someone was speculating that Google might be planning to move their Android OS to Netbooks. Well it looks like they had a different plan for Netbooks: Google Chrome OS. Take their fairly robust browser and bolt Linux onto it, and you have an OS specifically designed to run web applications . . . . like Google Docs, GMail, etc. And it can run on your Desktop too!

And thanks to Mono and Moonlight you can run Silverlight applications under it as well.
